Abstract
A winding mechanism for winding a narrower web has a drive shaft with a torque transmitting member fixedly mounted thereon, and a holder rotatably mounted on the drive shaft with a spring disposed around an outer circumferential surface of the holder with cushioning members interposed therebetween. Stoppers are disposed respectively in three chambers defined in the holder. A groove is defined in an inner circumferential surface of a winding core around which the narrower web is wound, and the cushioning members are fitted in the groove. A pressing force of the spring is applied through the stoppers to the winding core which is mounted on the holder.
Claims10
An apparatus for winding a web, comprising:
- a plurality of winding mechanisms each having a holder rotatably mounted on a drive shaft, a torque generating means for generating a torque for rotating the holder, joined members having joining grooves, and lock means for preventing a winding core from being detached from said holder when the web is wound around the winding core;
- said winding mechanisms being joined together as a joined array by winding mechanism joining members fitted in said joining grooves.
